Very unusual piece; so much so that I'm not sure what this is. Here's what I think -- turn-of-the-century, arts & crafts period sterling silver and brass face mask that could be a necklace pendant, belt buckle, bracelet focal point or clothing ornament. In fact, it could be all four depending on the fittings. Notice, there are six large loops or bails on the reverse. You could add a substantial chain to use as a pendant; use a heavy thread to attach to and adorn a winter coat; or, thread leather strips to make it a belt buckle. The face looks Germanic or Scandinavian and reminds me of a death mask. This is very well designed and constructed. Condition is very good to excellent. There are no marks or hallmarks. This pendant / focal point measures 2 1/4" x 2."
